TOOL FOR REMOVING VALVES FROM EXPLOS IVE-ENGINES.

Application filed November 23, 1918, Serial No. 263,840. Renewed November 17, 1919.

To all whom it may concern: 1

Be it known that I, CARL R. GLAsscooK, a citizen of the United States, residing at Springfield, in the county of Sangamon, State of Illinois, have invented certain new and useful Improvements, in Tools for Bemoving Valves from Explosive-Engines; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to tools for removing valves from explosive engines and it has for its object to provide an extremely cheap and simple article that may be used to compress the valve spring by raising its lower end, to permit of withdrawal of the cotter-pin, the tool serving to hold the valve in its seat as the spring is compressed.

The object of the invention is to provide a tool that may be used on various makes of engines that will be extremely simple and cheap of manufacture and which will have improved means for holding it set in place so that the operator may have both hands .freefor the work of removal or replacement of the pin.

In the drawings Figure 1 shows the tool in elevation and in use, a portion of an explosive engine being shown.

'Fig. 2 is a plan view of the pronged jaw member of the tool.

Referring now to the drawing, the pres' ent tool is in the form of a pair of tongs which includes the handle members 5 and 6 "which are crossed and pivoted at 7 beyond members and the jaw members in the same plane and the jaw member 9 at its extremity is provided with a prong 12 that lies at right angles to its plane, the sides of the Specification of Letters Patent.

Serial No. 338,761.

prong being at opposite sides of the continuation of the axis of the point 10 of the jaw member 8.

The handle member 5 extends beyond the i free end portion of the handle member 6 and is turned at an angle in the direction of the member 6 and upon its outer face is provided with a rack 13. The handle member 6 is perforated at its extremity and provided with a ring 14 which is adapted to engage successively the various notches of the rack 13 and hold the extremities ofthe jaws of the tool in correspondingly different correlative positions.

It will be noted that the handle member 5 adjacent the pivot 7 extends at an obtuse angle to the grip portion of the handle member 5 so that when an article is gripped between the points of the gripping jaws and the handle members squeezed together, the rack 13 that lies beyond the free end of the member 6 is swung in the direction of this free end so that the loop orring 14 ma be easily swung out of engagement with the rack. Conversely, when the handle memhere are released, the rack moves in such a directipn away from the pivotal mounting of the ring or loop as to preclude accidental disengagement of the ring from the rack.

In practice, the tongs are opened and the plug above the valve having been removed the extremity 10 is passed into the valve chamber and is engaged with the valve. At the same time, the prong 12 is adjusted to receive the valve stem below the usual washer on which the valve spring rests.

members are brought together with the result that the washer and the lower end of the spring are raised. The loop 14 being then swung into engagement with the proper tooth of the rack 13, the operators hands are free for the work of removing the pin.

When the operation is completed, the handle members are pressed toward each other so as to swing the rack toward the free end of the member 6. The loop may then be swung out of engagement with the rack and the tongs removed from the work.

What is claimed is: i

A pair of valve manipulating tongs comprising a pair of pivotally connected levers one of which has a semi-circular jaw at one end and at the other end a handle provided Bli with a terminal pivoted loop, the other lever gagement of the loop with its teeth interincluding a straight jaw with a terminal changeably. 1O
